Product details

Zener TVS for 23.1V rail clamping

The 1N6281ARL4 is a unidirectional Zener TVS diode from onsemi's Mosorb™ series, designed to clamp transients on a 23.1V nominal rail (reverse standoff) with a minimum breakdown of 25.7V and a maximum clamping voltage of 37.5V at peak pulse current. Rated for 1500W (1.5kW) peak pulse power over a junction temperature range of -65°C to 175°C, it suits high-reliability environments such as industrial power supplies, automotive modules, and telecom line cards where surge immunity is critical.

Through-hole axial package and mounting

Housed in a DO-201AD axial-lead package, the 1N6281ARL4 is a through-hole component suited for wave-solder assembly.

onsemi lists the 1N6281ARL4 as Obsolete. For a BOM line requiring this exact order code, procurement must source through independent distributors or excess inventory channels.
